MIXING DEVICE.

tures of gasolene and air, it being among the objects of this invention to produce a device which is simple, which is capable of producing a uniform mixture, which is adjustable and easily operated.

In carrying the objects of my lnvention into effect, I provide an insert or washer member having a central perforated por-.

tion, the member being placed between the carburetor and intake manifold of the engine, preferably at the junction between said two parts. An opening is formed in the insert member so that air is led into the intake tube in a direction substantially at right angles to the line of flow of gaseous mixture. A controlling valve for this opening is operated by the driver of the car through a rod or other suitable means. By the use of this device I obtain a more efficient explosive mixture and prevent in a large degree the formation of carbon in the cylinder.

Referring to the accompanying drawings forming a part hereof, and in which similar reference characters denote similar parts,

Figure 1 illustrates a side view of the carbureter and manifold with my device in place, and

Fig. 2, a partial section through my device.

The carbureter 1 has a flange 2 directly opposite a similar flange 4 on the intake manifold or tube 3 of the engine. The insert member 5 a perforated portion 6 corresponding to the opening in the intake tube 3 and bolt holes 7 cooperating with bolts 8 to hold the carbureter, manifold and insert member together.

An extension 9 is formed on one side of Specification of Letters Patent.

the insert member 5 and has an opening 10 in communication with the atmosphere and leading into portion 6 in a radial direction. A gauze 11 held in place by cap 12 prevents dust from entering. sion 13 on extension 9 is provided with a needle valve 14 to close opening 10, the outer portion 15 of the needle valve being connected to rod 16 to be operated in a well known manner, as from the drivers seat.

The carbureter 1 is adjusted to give the proper amount of fuel for full load and the needle valve 13 setto allow a certainamount of air to enter from opening 10 the air impinging at right angles to the flow of gas and air, and mixing therewith to produce a more complete and uniform mixture for combustion. The opening may be varied from time to time by adjusting the needle valve 14 through rod 16.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

A mixing device comprising a flat elon gated member adapted to be inserted be tween a carburetor and manifold of an internal combustion engine, said member having a central opening, an extension projecting outwardly from one edge of said member having a longitudinal bore communicating with the opening of said member, said extension being at an angle to the longitudinal axis of said elongated member, a second extension connected with the first extension between the ends of the first exten sion and projecting laterally to a vertical plane through the first extension, a valve in the second extension for closing communication through the first extension, and a rod flexibly connected with said valve for operating the same.

In witness whereof I havehereunto set my hand at Indianapolis, Indiana, this 23d dayof April, A. D. nineteen hundred and twenty.
